+<b>gets</b> is used to read a line of data from
+<a href=../MISC/stdfiles.html>STDIN</a>. By default STDIN is the
+keyboard. <b>gets</b> continues to read characters until NEWLINE or EOF
+is seen.
+<p>
+
+<pre>
+Library: stdio.h
+
+Prototype: char *gets(char *s);
+
+Syntax: char read_line[80];
+
+ gets( read_line);
+</pre>
+
+<h2>Notes</h2>
+<ol>
+<li><b>gets</b> does NOT check the size of the buffer and overflow on the
+stack can occour. Because of this, you should use
+<a href=fgets.html>fgets</a> in preferance.
+<p>
+
+<li>The
+<a href=escape.html>NEWLINE</a>
+character is NOT placed in the buffer.
+<a href=fgets.html>fgets</a> will retain the
+<a href=escape.html>NEWLINE</a>.
+</ul>
